[PATCH] hwmon: (ntc_thermistor): Add Samsung 1404-001221 NTC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This adds the Samsung 1404-001221 NTC thermistor to the
NTC thermistor driver. As far as I can tell it is electrically
compatible with the Murata 47K NTC thermistor.

This thermistor is mounted in a variety of Samsung products.

The DT binding oneline is included, I see no point in splitting
that into a separate patch.
